UNITED STATES PATENT OFFICE.

EDWIN JARRELL, OF THORNTOWN, INDIANA.

IMPROVEMENT IN WAGON-TONGUE SUPPORTS.

Specieation forming part of Letters Patent No. 154,488, dated August 25, 1874; applicationled July 3,1874.

To all whom it 'may concern:

Be it known that I, EDWIN JARRELL, of Thorntown, in the county of Boone and State of Indiana, have invented a new and valuable Improvement in Tongue-Supports; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same,'referencebe ing had to the annexed drawings, making a part of this specication, and 'to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation `of a plan view of my tongue-support. Fig. 2 is a longitudinal sectional view of the same..

Fig. 3 is a transverse sectional view of the same.

This invention has relation to devices for supporting wagon -tongues, so as to relieve the horses necks from the weight thereof.

The nature of my invention consists in the employment in rear of the pivot-pin ofa drafttongue of an adjusting-screw and an elastic bearing therefor, as will be hereinafter explained; also, in the employmentin front of said pivot of a bridgestop, which will check` theupward throw of the draft-tongue.`

The following is a description of my invention:

ln the annexed drawing,'A designates an axle, and B Bthe hounds for' the draft-tongue C, which parts, with the following-described exceptions, are constructed in the usual wellknown manner. The tongue C is applied between the hounds B B, and connected to them by means of a transverse pivot-bolt, a. In front of this pivot-bolt a is a bridge-stop, D, which is secured upon the upper sides of the hounds at their front ends, and which is `raised above the same between its ends, as shown in Fig. 3. This bridge D will prevent the front end of the draft-tongue from being thrown up too high while descending a hill or suddenly stopping tlie wagon. In rear of the pivotbolt a arectangular hole is made vertically through the tongue C, in which hole is applied a bolt, d, and a spring, s. The bolt d is passed down through the spring s, and through a stirrup, e, and receives a nut, d', on its lower end, by means of which nut the spring can be more or less compressed, as circumstances require. Above the head of bolt d, and tapped through a cross-bar, b, which is secured rigidly upon the hounds, is a screw, c, against which the head of bolt d bears, thus sustaining the weight of the front part of the tongue, and relieving the horses thereof. By adj usting-screw c any desired angle of inclination can be given to the tongue.

In practice, I shall cover the wearing-surfaces of the tongue and hounds with metal, for the purpose of preventing undue wear.

I am well aware that a tongue-support, consisting of a spring attached directly to a' 2. The bridge-stop D applied to the houndsf in front of the pivot a and over the tongue, all 'combined as and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

EDWIN JARRELL.
